Hair treatment product and hair after-treatment product containing ether guanidines as active substances, for protecting from damage caused by chemical treatment and for repairing already damaged hair

摘要

The invention relates to ether guanidines of the general formulae (I); and/or salts or hydrates thereof, in which R¹=—CH₂—CH₂—CH₂—O—R³ where R³ is, independently of the others, hydrocarbon radicals having greater than or equal to 10 carbon atoms, where part of the ether guanidines has radicals R³ which are branched and part of the ether guanidines has radicals R³ which are unbranched, and R²=independently of the others H or an optionally branched, optionally double-bond-containing hydrocarbon radical having 1 to 30 carbon atoms, and use thereof in hair treatment compositions and hair aftertreatment compositions, in particular for preventing damage by chemical treatment compositions and for repairing hair which is already damaged.
